District News and Information

Holiday Reminder- FOG

In preparation for the upcoming Holidays the District would like your help to help us combat a shared enemy. FOG (Fats, Oils, & Grease) is the #1 cause of blockages in sewer system. When you experience a sewer backup in your home the most likely cause is FOG buildup which can become a costly mess.

Below is an example of what pouring fats, oils, or grease down the drain actually does. What we should do instead of going down the drain – COOK IT; CAN IT; OR TRASH IT!

If you do experience a sewer backup, or any other issue with your water or sewer utilities, please contact the Districts operator, Municipal District Services. You can reach them 24/7 at 281-290-6503 or visit them at www.mdswater.com

The community is invited to share their thoughts and ideas from now until July 30th, 2020, via one of the following methods:

HMCMUD 386 Water Bill Notice- June 2, 2020

In an abundance of caution during the COVID-19 emergency, water usage on your April bill was averaged using your previous 4 months of actual water usage at your residence. Meters were read in May and the May water bill reflects the actual reading and usage.

In your March water bill, we informed you that the North Harris County Regional Water Authority (NHCRWA) fee was scheduled to increase from $3.97 per 1,000 gallons of water to $4.68 per 1,000 gallons. The NHCRWA rescinded the increase due to COVID-19 and therefore the District did NOT pass this increase on to you. It is unclear if or when the NHCRWA will increase their fee; if they do, the District will then pass the increase on to its customers.

For updates, visit us at www.hmcmud386.org or call Municipal District Services at 281-290-6507.

Emergency Operations Update June 5, 2019- 4:00 p.m.

Harris-Montgomery Counties MUD 386 is actively monitoring tropical activity in the Gulf of Mexico that is forecasted to impact the Houston area throughout today, Wednesday, June 5th and tomorrow, June 6th. Currently 4-6 inches of rainfall is forecasted through Thursday, June 6th.

Why is there a Flash Flood Watch tonight through Thursday morning?
The US National Weather Service Houston-Galveston Texas issued the watch due to potential high rainfall RATES over the next couple days. We’re not expecting a high TOTAL amount of rainfall, but it’s hard to predict right now what areas will see rates as high as 2-3 inches per hour.

What does this mean for you?
It sounds basic, but if it seems like it’s raining hard, it probably is. If you’re driving and get caught in the heavy rainfall, exercise extreme caution. If you’re driving when the rain moves in, get off the road and to a safe, high, place since flash flooding can occur on streets and low areas.

How can you prepare?
First: Today and tonight before it gets dark you can clear drains, ditches, gutters, and curbs of debris that can wash into drains and cause street flooding. Stay hydrated and be mosquito smart! If you have a yard crew coming today, tell them not to blow your yard waste into the road.
Second: Secure anything in your yard that could wash away if it rains hard on your property.
Third: Check the weather before you go, since the rain is hard to predict and can quickly cause flooding. Plan around the storms if you can since flooded roads can stall your car leading to permanent or expensive damage to your vehicle.

Rivers and Flooding
Right now our rivers are high but well within their banks. Unless the situation changes dramatically, we are not expecting any river impacts at this time. If rain falls at a rate of 3 inches per hour or more, isolated areas may see some flash flooding.

How often should I water my lawn?

Watering infrequently and deeply is the key to a healthy Texas lawn. This technique helps plants grow longer, tougher roots that will allow them to access water throughout the summer even as temperatures rise.

How much water does grass need?

Typically, the average Texas lawn only needs about an inch of water per week, even in the hottest summers. If you’re unsure how long it takes to reach an inch of water, you can put a cup or can in your yard with an inch high marker and then time how long it takes to fill. In general, automatic irrigation systems disperse water at a much quicker rate than hose-end sprinklers. Start with shorter times and add additional time if large areas of damaged or dried-out grass appear. Of course, if there has been significant rainfall recently, you do not need to re-water.
